Extension Study of Biostate in Subjects With Von Willebrand Disease

This study has been completed.
Information provided by (Responsible Party):
CSL Behring Identifier:
First received: June 8, 2010
Last updated: April 8, 2014
Last verified: April 2014
The aim of the Von Willebrand Disease (VWD) therapy is to treat and prevent bleeding episodes due to abnormal platelet adhesion and abnormal blood coagulation as a result of low or abnormal Von Willebrand Factor (VWF) and/or Factor VIII (FVIII) levels. The long-term efficacy and safety of a VWF/FVIII concentrate, Biostate, will be investigated in children, adolescents, and adults with VWD in whom treatment with a VWF product is required for prophylactic therapy, haemostatic control during surgery, or control of a non-surgical, spontaneous, or traumatic bleeding event.

Condition Intervention Phase
Von Willebrand Disease Biological: Biostate Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open-Label, Multi-Centre Extension Study to Assess the Efficacy and Safety of Biostate® in Paediatric, Adolescent, and Adult Subjects With Von Willebrand Disease Who Completed Clinical Studies CSLCT-BIO-08-52 or CSLCTBIO-08-54
